ANU Research Helps Plants Ability to Naturally Preserve Water

Australian ​National ​University,​ ​Canberra ​biologists have ​found a new way ​to help plants ​survive drought ​by enhancing ​their ​natural ​ability to ​conserve water.​  ​

The research ​team mapped the ​chemical ​signals used by ​plants to ​close the pores ​on their leaves ​and restrict ​water loss ​in drought ​conditions.​  ​

The study, ​published their ​research ​in eLIFE, ​found ​chloroplasts ​in cells ​surrounding the ​pores on leaves,​ called stomata,​ can sense ​drought stress ​and thereby ​activate a ​chemical signal ​that closes ​stomata to ​conserve water. ​

By enhancing ​the chloroplast ​signal on ​plants used in ​the experiments,​ barley and a ​small native ​weed called ​Aradbidopsis, ​researchers ​found they ​survived 50 per ​cent longer in ​drought ​conditions.​  ​

The research ​team, led by ​Dr ​Wannarat ​Pornsiriwong, ​Dr ​Gonzalo ​Estavillo, Dr ​Kai Chan and Dr ​Barry ​Pogson, hope ​the research ​leads to ​benefits ​for major ​crops such as ​barley, rice ​and wheat, ​which are ​crucial to ​world food ​supplies. ​
